I could never play the ingenue, the girl next door or the very successful young doctor. That would be a bore.
If you want something, have it. If you feel like it's forbidden, you'll want it even more. Whenever I have a craving, I go and have it and just make sure I don't have it again the next day.
During the work, you have to be sure that you haven't left any holes, that you've captured everything, because afterwards it will be too late.
